clean fuel jet in carburetor or buy a new one for 30.00

Sounds like the jets are clogged. You may need to rebuild the carb.

The manual is on this link: http://engines.honda.com/parts-and-support/owners-manuals/GCV160 The manual depends on the serial number. It does not appear to have adjustable choke.

Firstly, if it's fuel injected, there is no choke. That cold start mode is actuated by the computer. IF it has a carb on it, the choke is opened a little to keep it running with a vacuum line connected from the choke dashpot to the carb base when cold till warm-up, then a heat spring pulls the choke full open. Your gonna have to make up your mid as to whether it fuel injection or natural aspiration with a carburetor.

too much fuel going through the top of the engine (engine wash).
like having the choke out all the time.....or running too cold.

yes your carb is probably dirty try sea foam or small engine tune up or get your carb cleaned

Karcher Model G2650 OH with Honda 6.0 HP, GC 190 Engine. Engine won't start. New gas, has spark. Seems to flood instantly. Much gas in cylinder. Spark plug wet. Choke pulled out, power on. Oil OK. released pressure in line. Where can I down load a Honda Engine manual! Thank you !

Not to sure about this one, ok, if the choke wont stay out, then try to trace the choke cable to the carby, have a close look and see which parts move on the carby when you activate the choke, some thing just needs to be tightened up, so that the choke stays on. Also, you say the bike stalls and runs rough, is this with the choke on? If yes, then that is just a sign that you dont need so much choke on. Just try half choke. Do you live in a warm climate? if so, then you dont need much choke . So there is no adjustment really, only by the amount of choke you apply. Also remember, never use the choke if the engine is already warm. And, only use the choke for the first start of the day, when the engine is stone cold. The correct way to to start a cold bike engine is, pull the choke on fully, crank over engine, but DO NOT give it throttle, (this defeats the purpose of using the choke), when engine fires up and starts, slowly push the choke in till a smooth, high idle is acheived. You should be able to ride off slowly, and push the choke off after about a mile.

sounds like it may need the carb clening out, but it could be the auto choke not closing when cold. there was an issue with some of the early auto chokes on the gcv135/160 engines so check to see if the choke flap is in the closed position when starting from cold, run the engine for approx 10-15 minutes and see if the choke flap has opened fully.leave it to go cold and see if the choke flap has returned to the closed position
